Rice Husk Grinder Machine
Turn Rice Husk Waste into Profit
Rice Husk Grinder Factory Direct
Do you want to grind only rice husks, or mix in other materials as well? Are the rice husks dry or wet? How fine do you need the output to be? Is it for livestock feed, bedding for farm enclosures, or for making pellet fuel? Approximately how many tonnes do you plan to process per day? Please feel free to send a private message with details about your material, daily processing volume, and intended use; we can then recommend the right model and provide full details on output, power, and pricing.
Our rice husk grinder machine delivers a capacity ranging from 0.5–50T/H, varying according to raw material properties. Its output particle size is adjustable between 0.5mm and 20mm, with a price range of $5,000–$35,000. We supply matching auxiliary equipment. If feedstock includes straw, wood chips or other materials over 5cm, we offer primary crushers to reduce them to 2–5cm before fine grinding. For high-moisture materials, dryers are available for pre-drying prior to grinding.
Technical Advantages
RICHI rice husk grinding machine has undergone systematic optimization across multiple dimensions—including grinding performance, durability, operational efficiency, ease of maintenance, and safety compliance. It is characterized by uniform grinding, high output, low energy consumption, ease of maintenance, and safe, stable operation, enabling it to meet production demands under the continuous, rigorous conditions associated with various biomass materials.
Excellent Grinding Performance
The high-speed rotor running at 2980 rpm generates strong impact force for thorough material crushing. The finished particle size is adjustable. By replacing screens with different hole sizes, the discharge particle size can be flexibly set within the range of 0.5mm–20mm.
Wear-resistant Hammers and Robust Machine Body
Quenched high-carbon steel hammers feature high hardness and great wear resistance. The 5 mm thick hammers are double-sided usable for longer service life. Double-layer side plates (6 mm outer +10 mm inner) withstand heavy impact and ensure strong rigidity and stable operation.
Stable Drive System
Our rice husk grinder uses a Siemens motor, delivering abundant power with lower energy consumption. Current fluctuation ≤10% during crushing for higher energy efficiency. Rotor dynamic balance test before delivery ensures low vibration and noise at high speed.
Variable Frequency Feeding Design
You can add an impeller feeder to this grinding machine. A variable-frequency motor controls feeding to keep material supply even and stable, so the mill won’t choke easily. The impeller blades keep stirring and pulling material to stop material bridging.
Easy Maintenance Structure
The fully openable movable access door removes hard-to-reach dead corners, making it easy to clear accumulated materials and replace hammers. The linked screen-clamping mechanism supports fast screen mounting and dismounting, enabling on-site adjustment of output particle size. The whole machine features low maintenance requirements and a low failure rate.
Multiple Safety Protection
An interlocked safety system links the access door, protective housing and start-stop controls. The machine cannot start unless the access door is fully closed. If the access door or guard is opened during operation, the machine shuts down immediately. A spark detection and extinguishing system is available as an option to reduce the risk of dust explosion.

additional pretreatment equipment
Before purchasing a pulverizer, consider three key factors: Do the raw materials require preliminary crushing? Does wet material need to be dried first? Who is the target market for the finished product? We offer not only rice husk hammer mills but also complete equipment solutions—including upstream crushing, drying, and downstream packaging machinery—tailored to your specific raw material requirements.
FAQ
How much does a rice husk grinder cost? wood chips generates a large amount of wood dust; do you have a way to control it that meets environmental inspection standards?
→
The price of a rice husk grinder depends primarily on its capacity and configuration, generally ranging from $5,000 to $35,000. If you let us know your target processing volume and desired output fineness, we can recommend a suitable model and provide a price quote.
What is the hourly output?
→
Production capacity varies depending on the type of raw material and its moisture content. With the same machine, a finer screen results in lower output, and wetter material also reduces output; therefore, before providing a quote, we will select the appropriate model based on your specific production requirements.
Can wet rice husks be processed? Will it cause clogging?
→
If the moisture content is too high (exceeding 18–20%), it is recommended to install a rotary dryer first; this ensures more stable output and fineness. Otherwise, the high moisture content of the raw material can easily clog the screen.
Can crop stalks and corn cobs be ground together?
→
Our rice husk grinder machine can directly process materials such as rice husks, peanut shells, sunflower seed hulls, and coffee husks, provided they are smaller than 3–5 cm in size. However, for long-fiber materials like crop stalks or larger items like corn cobs, additional coarse crushing equipment is required.
Are the hammer blades and screens durable? How often should they be replaced?
→
Our rice husk grinder machine is equipped with tungsten carbide hammers that have undergone carburizing and quenching treatments, offering exceptional wear resistance. The hammers are reversible, giving them a significantly longer lifespan than standard ones. The screens are made of thickened material and are highly resistant to breakage. Actual service life depends on the material being processed; harder materials like corn cobs will cause faster wear, which is considered normal.
Can I test the machine? Can I visit the factory to see it?
→
Yes, you are welcome to bring your raw materials to the factory for a live test. We can discuss further once you are satisfied with the output results. If you are located far away, I can send you a video of the same model being tested for another client, which will serve as a useful reference.
What is your warranty service like?
→
We provide a one-year warranty on the entire machine, as well as installation guidance, operational training, a supply of wear parts, and support via remote guidance or on-site repair. (view our YouTube)
